Title: Luminance signal chrominance signal separation circuit
Inventor: KAI TOSHIHIRO
IPC: H04N9/78
Filed: 1999-05-17
Abstract: PROBLEM TO BE SOLVED: To obtain a luminance signal chrominance signal separation circuit where no dot disturbance takes place even when a color transient is laterally in existence or chrominance signals are changed between lines. SOLUTION: This luminance signal chrominance signal separation circuit is provided with a color signal extract filter 101 with a variable pass band that extracts a chrominance signal from a composite video signal v, a luminance signal extraction filter 701 that subtracts a color output from the signal (v) to obtain a luminance output, a longitudinal dot frequency component extract filter 201 that extracts a longitudinal dot component around 1/2 of a line correlation frequency and around 2/3 of a chrominance carrier frequency from the signal (v), a nonlinear lateral dot frequency component extract filter 301 that extracts a lateral dot component around 1/4 of the line correlation frequency and around the chrominance carrier frequency from the signal (v), a reference signal extract device 501 that extracts a prescribed frequency component of the signal (v), and a comparator 601 that obtains a comparison output between the longitudinal dot component and the reference component. When this comparison output includes many of the longitudinal dot components, the pass band of the chrominance signal extract filter 101 is switched to include the longitudinal dot frequency region.

Title: Piping mounting structure
Inventor: SEI MIKIO
IPC: F16L59/14
Filed: 1997-05-26
Abstract: PROBLEM TO BE SOLVED: To prevent freezing of water flowing in piping by providing a gap between the overall outer peripheral surface of the piping, an exterior-wall heat insulating material, and an interior wall material with a support member between them, and using the gap as a ventilating layer communicated to the interior. SOLUTION: An exterior-wall heat insulating material 3 is provided between an exterior wall material 1 and an interior wall material 2. Piping 4 is passed through the support ring 5a of a support member 5, the support ring 5a is secured to the piping 4, and a peripheral ring 5C is made to abut to the exterior wall heat insulating material 3. Further, a gap is provided between the overall outer peripheral surface of the piping 4, the exterior wall heat insulating material 3, and the interior wall material 2 with the support member 5 between them and is used as a ventilating layer 6 communicated to the interior 10.  Warm air near the floor of the interior 10 flows into the ventilating layer 6 from an air vent 9 located near the floor, rises within the ventilating layer 6 while warming the piping 4 from its bottom, and then flows out to the interior 10 from the air vent 9 near the upper end of the piping 4. Thus, since the piping 4 is warmed, freezing of water passing through the piping 4 can be prevented.

IPC: G01N35/10
Filed: 1988-06-03
Abstract: PURPOSE:To improve the safety and the operability of an analyzer by providing operation annunciating means on a sampling arm and reagent arms. CONSTITUTION:A sample is injected into a reaction tube 13 facing a position A under the state wherein the reacting tube is stopped. At this time, a CPU 18 sends a signal to a sampling-arm driving control part 20 in accordance with a predetermined program. A sampling arm 14a is turned to a sample cell 14c with a shaft 14b as a supporting point. The CPU 18a also sends a signal to a lamp 17a through a lamp driving control part 19 before the turning of the arm 14a. The lamp 17a is lighted, and the turning of the arm 14a is announced beforehand. Then, the arm 14a is lowered, and the sample is sucked out of the sample cell 14c. The CPU 18 sends a signal before the arm is lifted up again, and the lamp 17a is lighted. When the arm 14a is stopped on the reacting tube 13, a light-out signal is sent and the operation annunciation is finished. When first and second reagents are injected, lamps 17b and 17c are lighted by the same way. Thus, the operations of arms 15a and 16a are annunciated beforehand.

The image can be repeatedly formed and erased. As the reversible coloring agent layer, a composition containing an amphoteric compound and a leuco compound is used. The amphoteric compound is a salt of a compound containing at least one of phenol hydroxyl group and carboxyl group, and amino group, as shown by a formula I, and an aliphatic amine. In the formula, X represents hydroxyl group or carboxyl group, and R represents hydrogen atom or hydroxyl group.

IPC: B60K17/35
Filed: 1994-06-17
Abstract: PURPOSE:To provide a driving force control device for a four-wheel drive vehicle with which a turning condition can be detected securely. CONSTITUTION:Wheel speed sensors are provided to detect wheel speed of four wheels respectively, and differential speed DELTANR, DELTANL between a front and outer wheel and a rear and inner wheel is calculated (steps 100,150). When DELTANL is a determination value N1 in accordance with differential speed at a turning radius at which a tight corner brake is generated or more, and less than a determination value N2 in accordance with differential speed at the minimum rotation radius, it is judged as a turning condition at a large steering angle (steps 110, 120, 160, 170). When it is judged as the turning condition at the large steering angle, a differential limiting clutch is controlled to decrease transmission torque (step 130), thereby generation of tight corner brake phenomenon can be prevented.

Title: Door mirror drive device
Inventor: YAMAMOTO YUKIO
IPC: B60R1/06
Filed: 1986-06-13
Abstract: PURPOSE:To improve hardiness of a door mirror by driving a drive motor for housing and restoring the door mirror for a certain time when vehicle speed is found to be equal to or more than a predetermined value by a vehicle speed switch whereby resetting the door mirror at its restored position automatically. CONSTITUTION:While a vehicle is running with its door mirror housed in, when vehicle speed is equal to or more than a predetermined value (for example, 10km/h), a vehicle speed switch 11 is turned on for actuating a timer device 12 so as to excite an exciting coil 14. Then, relay contacts 15 and 16 are turned on by said exciting coil 14, thereby sending current from a battery 5 to drive motors M1 and M6 so as to restore the door mirror main body to the condition of its practical use, and then a timer device 12 is turned off after a certain time elapses. And when the timer device 12 is actuated with the vehicle speed switch 11 turned on, current flows into an exciting coil 20 because of potential difference with the exciting coil 14 whereby a relay contact 17 is turned on and relay contacts 18 and 19 are turned off, thereby preventing the timer device 12 from being reactuated from that time on.

Title: Luminaire
Inventor: TANAKA WATARU
IPC: F21V7/22
Filed: 1999-05-18
Abstract: PROBLEM TO BE SOLVED: To provide a luminaire being capable of using a highly heat-resistant resin for a main body without limiting a color and a low heat-resistant, cheap resin for a frame while making the luminaire compact. SOLUTION: A main body 1 formed with a resin substrate to surround a light source 4 and a frame 2 closing a space between a ceiling opening and the main body 1 are integrally formed to provide a reflecting plate 3. The main body 1 is formed with a highly heat-resistant resin and a high brightness metallic reflecting film 12 is formed on the surface of the resin substrate, whereby a light-reflecting function is provided. The frame 2 is formed with a white general-purpose resin and is disposed not to be directly illuminated with light from the light source 4. Consequently, a different material can be used for the main body l and the frame 2. Because the main body 1 is provided with the high brightness metallic reflecting film 12 to secure the light-reflecting function, the color of the highly heat-resistant resin does not need to be limited, whereby choices increase.  Because the frame 2 has an extremely small influence from heat and ultraviolet light, it is possible to use a low heat-resistant, cheap resin.
